❣️Hola mate,
❣️Here is your answer.. :)
A flash of light in the sky caused by an electrical discharge between clouds or between a cloud and the Earth's surface.
Explanation:
Lightning is a large-scale natural spark discharge that occurs within the atmosphere or between the atmosphere and the Earth’s surface.
Lightning is visible as a flash of blue-white light. The extremely high temperatures generated heat the air molecules to a state of incandescence (white hot) such that they emit a vivid white light. At the same time, nitrogen gas (the dominant gas in the atmosphere) is stimulated to luminesce, producing bright blue-white. The combination of light from luminescence and incandescence gives the bolt of lightning its characteristic colour.
